Light of wavelength 6000 Armstrong in air enters a medium of refractive index of 1.5 . What are the wavelength and frequency of light in that medium? Can you please tell me that why I should take. v=3*10(raised to 8)/6000 Armstrong. Instead I can take v=3*10(raised to 8)/4000 Armstrong , because wavelength of light in that medium is 4000 Armstrong.
Considering 371 to be an Armstrong number we will multiple the cube of each individual digit and then add the sum of each digit. For example: 371 = (3x3x3)+ (7x7x7)+ (1x1x1) where: 3 cube=27. 7 cube=343. 1 cube=1. Now we add the sum of all the cubes together: 27+343+1=371.
Nov 26, 2021 · $\begingroup$ First mention of Armstrong number in print that I could find: F. D. Federighi and Edwin D. Reilly, "Computer Science Laboratory Exercises", Schenectady, New York: Reidinger and Reidinger 1971, p. 9: "An n-digit number is an Armstrong number if the sum of the nth power of the digits is equal to the original number. Therefore, 371 ...
Verified by Toppr. The angstrom (˙A) is an internationally recognized unit of length equal to 1×10−10m. It is not a part of the S.I. system of units, but it can be considered as a part of the metric system. Was this answer helpful? 7. Similar Questions. Q 1.

False. The double helix DNA turns after every 10 base pairs at a distance of 3.4 nm. This distance is called pitch. The distance between two base pairs is 0.34 nm. Hence, the statement given in the question is correct.
One or more of these sections may be incorrect. You need to identify the section and pick the number for the section. The correct sentence can be written as: People believe in the medicine that the government dispensaries have. So the correct option is A) (1). Q 2: (1) She walking (2) briskly (3) meant that she was in a hurry.
To check if 371 is an Armstrong number or not, we will have to check whether 371 is equal to the sum of the cube of its digits: For example: 371 = (3x3x3)+ (7x7x7)+ (1x1x1) where: 3 cube=27. 7 cube=343. 1 cube=1. Now we add the sum of all the cubes together: 27+343+1=371.
Similarly, 169 is the square of 13 and we can reach the answer in two easy steps: Step 1: Find the square of the number “one” below the given number (which is 13). The number is 12 and 122 = 144. Step 2: Subtract this value of the squared number from the given number i.e. 169 -144 = 25. Therefore, the answer is 25.
Rydberg Formula. 1 λ = RZ2(1 n21 − 1 n22) Where. The wavelength of the photon. Integers where n2> n1. It was later found that n2andn1 were related to the principal quantum number or energy quantum number. This formula works very well for transitions between energy levels of the hydrogen atom.
